Description

一种带有自浮动内芯的光纤连接器 技术领域
本发明涉及一种光纤连接器，具体涉及一种带有自浮动内芯的光纤连接器。
背景技术
室外光纤连接器广泛应用于室外RRU设备中，在RRU设备中，其光纤接口多为图19所示形式，包含内置的光模块插头和外部的插座。光模块插头用于与光纤连接器对接后传输光信号，插座与光纤连接器的外壳体配合，起到连接器的抗拉和密封作用。
然而在实际应用过程中，不同厂家的光模块安装位置不同，光模块插头的轴向尺寸不一致，如图19所示，因此要求适配的光纤连接器具备较高的通用性，即连接器需具备轴向可调功能以适配不同厂家的设备要求。
现有室外光纤连接器的结构特点通常包含插头组件、浮动机构，浮动机构包括外壳体、支架和粘接套。支架可沿轴向相对粘接套移动，外壳体可以相对支架旋转并移动，外壳体前端设置与插座相配合的锁紧结构。粘接套上设置有锁齿，支架尾端设置有锁爪，相邻两个锁齿间形成与锁爪相配合的锁槽，外壳体内壁设置与锁爪相配合的内锥面，用于锁紧锁爪，实现连接器的锁紧及抗拉功能。
使用时，操作人员先将插头组件插入对应的插座中，调整支架相对于粘接套的位置，然后移动外壳体，外壳体上的连接结构与插座上的相应结构配合实现锁紧，外壳体向前移动的过程中，外壳体的内锥面挤压支架上的锁爪使其卡在锁槽中，实现线缆的抗拉。
现有技术的缺点：
1、现有结构只能实现沿轴向，即连接器对插方向单一方向的偏摆。
2、现有结构进行轴向距离调整的方式为步进式，调整距离为粘接套相邻两锁槽中心距离的整数倍。当调整距离不是中心距离的整数倍时，使用过程中，当支架移动调整距离后，锁爪不会直接落入锁槽中，而是在外壳体相应锥面的推力作用下，落入其他锁槽中，使得支架与标准的调整距离之间具有一定的偏差，由此引发两个问题：
(1)锁爪落入粘接套靠后的锁槽时，粘接套前端的分支光纤受拉，拉力过大时会导致光纤断裂，传输信号中断。
(2)锁爪落入粘接套靠前的锁槽时，粘接套前端的分支光纤受挤压， 插头组件中插针回退会带动分支光纤向后运动，在现有技术中，每根分支光纤外侧均套设空心束管或铠甲束管，因分支光纤外侧套设的空心束管或者铠甲管空间有限，分支光纤在其内部过分弯曲产生弯曲应力，也会导致光纤折断，传输信号中断。
3、由于上述第2条缺点导致该种结构对光缆分支端余长要求严格，装配过程难度较大，产品装配及使用时故障率较高。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明一种带有自浮动内芯的光纤连接器的实施例一，如图1至图12所示，该连接器包括内芯部件、支架6、外壳体7，内芯部件包括插头组件1、支撑套2、粘接套3、尾部护套4。该连接器与光缆5连接，并插装在RRU设备的插座上，使插头组件1与RRU设备的光模块插头插接。
插头组件1包括插头上壳体101、插头下壳体102、多个内芯插头103，内芯插头103的尾部卡在插头下壳体102内，插头上壳体101通过卡扣结构罩盖固定在插头下壳体102上，并固定内芯插头103。
光缆5穿过尾部护套4并穿入粘接套3，光缆5在粘接套3内分出多根分支光纤501，分支光纤501依次经过粘接套3、支撑套2后与对应的内芯插头103连接。以光缆5延伸的方向为轴向，与轴向垂直的方向为径向，以插头组件1为前端部。
支撑套2主体在径向上的截面形状为矩形，支撑套2沿轴向设置供分支光纤501穿过的内部空腔201，支撑套2外壁设置凹槽，凹槽包括支撑套凹槽Ⅰ203、支撑套凹槽Ⅱ204。支撑套凹槽Ⅰ203开设在支撑套2的宽边上，支撑套凹槽Ⅱ204开设在支撑套2的窄边上，并且支撑套凹槽Ⅰ203、支撑套凹槽Ⅱ204的延伸方向均与轴向相互垂直。支撑套凹槽Ⅰ203、支撑套凹槽Ⅱ204在轴向上相互交错排列，使支撑套2被拉伸、压缩或者弯曲时，实现内芯部件的微量偏摆。
支撑套2作为独立元件，其形状及尺寸可根据具体的使用场景及其内 部所容纳的分支光纤数量和长度决定，例如，在本实施例一中，支撑套2主体在径向上的截面形状为矩形，在实施例二中，支撑套2主体在径向上的截面形状为圆形，如图13所示，在其他实施例中，支撑套2主体在径向上的截面形状可以是椭圆形或其他形状。支撑套2上环向分布多个凹槽组，每个凹槽组中的多个凹槽在轴向上对齐，且多组凹槽中的凹槽相互交错分布在支撑套2上。
支撑套2上交错排列的凹槽可以为通槽或者非通槽，通槽与支撑套2的内部空腔201连通，非通槽与支撑套2的内部空腔201不连通，在本实施例一中，支撑套2上的凹槽为非通槽，在实施例三中，支撑套2上的凹槽为通槽，如图14所示，凹槽的延伸方向设置根据连接器所需的弯曲方向决定，由于支撑套2上环向分布多个凹槽组，支撑套2可以在任意方向上实现弯曲，凹槽为连接器弯曲提供避让空间。
支撑套2使用橡胶等柔性材料制成，在外力作用下可被拉伸或压缩，因此可实现拉伸及压缩功能，同时支撑套2的内部为空心结构，其内部空腔的直径大于容纳的所有分支光纤的外径，可容纳多芯光缆的多根分支光纤在其内自由伸展或弯曲。
支撑套2前端设置与插头组件1相配合且沿轴向延伸的连接凸起207，连接凸起207内设置与内部空腔201连通的通孔，以供分支光纤501穿过，连接凸起207的前端部设置卡块208。连接凸起207的外壁环向设置连接凸键202，插头下壳体102尾部设置供分支光纤501经过的通槽，插头下壳体102的通槽与连接凸起207相匹配，且该通槽的内壁设置与连接凸键202匹配的连接凹槽10201。将连接凸起207嵌套在插头下壳体102的通槽内，卡块208卡在插头下壳体102的空腔内，然后在插头下壳体102上罩盖固定插头上壳体101，使得卡块208被限位在插头下壳体102的空腔内，实现支撑套2与插头组件1之间的抗拉功能。在卡块208卡入插头下壳体102的空腔内的同时，连接凸键202嵌套在连接凹槽10201内，罩盖固定插头上壳体101后，进一步增强支撑套2与插头组件1抗拉功能，如图15所示。在本发明的其他实施例中，根据相适配的插头组件的对应结构决定连接凸起207的形状，如果插头下壳体102上设置连接凸键，连接凸起207上可以设置与连接凸键匹配的连接凹槽，保证插头组件1与支撑套2的可靠连接。
支撑套2的后端部设置与粘接套3相配合的限位键206、加强凸起209，支撑套2后端部的外壁设置两个限位键206，这两个限位键206在径向上延伸并对称设置，粘接套3前端部内腔的内壁上设置与限位键206相匹配的限位键槽305，实现机械限位及防转功能。加强凸起209轴向延伸，其上设置轴向延伸且与内部空腔连通以供分支光纤穿过的通孔，加强凸起209的
壁体上贯穿设置至少一个的灌胶孔205，粘接套3前端部内腔的灌胶区域304内灌胶时，胶液可流过灌胶孔205，固化后起到抗拉作用。将支撑套2的后端部插入粘接套3前端部的空腔，使得限位键206嵌套在限位键槽305中，然后向粘接套3内灌胶，使得支撑套2与粘接套3固定，如图16所示。
尾部护套4的前端部插入粘接套3后端部的空腔内，两者通过卡台卡槽结构进行固定，如图17所示。
如图18所示，支架6套设在内芯部件外侧，外壳体7套设在支架6及内芯部件外侧，外壳体7可以相对于支架6转动，并在转动过程中沿轴向相对于支架6前后移动。支架6的前端部外壁设置用于与插座插接密封的密封圈以及与插座、外壳体7配合的结构。外壳体7的前端部设置与插座相配合的锁紧结构，外壳体7向前移动时与插座相互锁紧。
支架6为回转体，其内部设置轴向贯通的空腔，支架6内腔的壁体上设置沿轴向的导向键605，粘接套3的外壁具有与导向键相配合的滑动键槽303，导向键与滑动键槽303一一对应，支架6可沿轴向移动，此时，导向键在滑动键槽303中滑动。支架6的壁体上设置轴向延伸且贯通壁体的悬臂孔602，悬臂孔602内设置轴向延伸的悬臂603，悬臂603的端部设置锁爪601，锁爪601朝向支架6的内腔延伸。粘接套3的外壁设置锁齿组，锁齿组高出粘接套3的外壁，两个锁齿组之间形成一个滑动键槽303，锁齿组与锁爪601一一对应，锁齿组包括多个沿轴向分布的锁齿301，相邻两个锁齿301间形成与锁爪601相配合的锁槽302。当导向键605、悬臂603设置多个时，导向键605与悬臂603环向间隔分布在支架6的壁体上，对应的，锁齿组、滑动键槽303环向间隔分布在粘接套3的壁体上。
外壳体7上设置内锥面701，内锥面701朝向前侧，用于锁紧锁爪601。悬臂603与锁爪601相对的外壁设置凸块604，外壳体7向前移动时，内锥面701挤压凸块604，实现锁爪601与锁槽302的牢固配合，从而实现连接器的锁紧及抗拉功能。
使用时，操作人员先将插头组件1插入对应的插座9中，与光模块插头10插接，调整支架6相对于粘接套3的位置，使支架6的前端部插入插座9中，并使锁爪601卡在对应的锁槽302中。如果支架6的调整距离是锁槽中心距离的整数倍，并且光模块插头10与插座9的相对位置与插头组件1与支架6的相对位置匹配，锁爪601卡在锁槽302内后，支撑套2没有拉伸、压缩或弯曲；如果支架6的调整距离不是锁槽中心距离的整数倍，当锁爪601卡在靠前的锁槽302时，支撑套2被压缩，当锁爪601卡在靠后的锁槽302时，支撑套2被拉伸；支撑套2拉伸或压缩，以适应调整距离，保证插头组件1与光模块插头的准确插合。当光模块插头10与插座9的相对位置与插头组件1与支架6的相对位置不匹配，锁爪601卡在对应 的锁槽302后，支撑套2发生弯曲，保证插头组件1与光模块插头的准确插合。锁爪601卡在对应的锁槽302内后，旋转外壳体7，使外壳体7前移，外壳体7上的连接结构与插座上的相应结构配合实现锁紧，外壳体7向前移动的过程中，外壳体7的内锥面701挤压支架6上的锁爪601使其卡在粘接套3对应的槽中，实现光缆的抗拉。
外壳体7与支架6的相对旋转移动结构以及与插座的锁紧结构均为现有技术，例如，在旋转移动结构中，支架6的外壁上设置如图4所示的波浪凸起，外壳体7的内壁设置凸块，外壳体7旋转，凸块在波浪凸起上滑动，使得外壳体7前后移动；在锁紧结构中，外壳体7可采用螺纹连接与插座固定。旋转移动结构以及锁紧结构也可采用其他结构，在此不再赘述。
支撑套2的微调功能可对现有结构进行修正，支撑套2的拉伸/压缩/弯曲功能与粘接套3的步进式浮动功能相配合，形成微调与粗调组合的两级浮动结构。锁爪与锁齿、锁槽构成一级浮动结构，当一级浮动结构无法满足浮动距离或角度要求时，可通过粘接套3的压缩/拉伸/弯曲功能来对一级浮动结构进行补偿。本发明的两级浮动结构也可应用于其他需要轴向位移调整的连接器中，支撑套2的微量调节功能能够保证连接器插头可靠对接而不会影响传输性能。
该连接器在装配过程中，支撑套2作为单一零件，使用支撑套2替代现有技术中如图20所示的多护套结构，支撑套2的内部为空心结构，光缆5的分支光纤在其中的回退空间增大，当支撑套发生压缩/拉伸/弯曲时，分支光纤501在支撑套2的内部可自由活动，一方面简化分支光纤501与连接器的固定方式，装配零件减少，操作过程简单，生产效率提高，另一方面插头组件1的前端至粘接套3的前端的光缆余长增大，进一步降低装配难度。
该连接器在使用过程中，出现连接故障时，维修检查时仅需去掉连接器的外壳体7，将外壳体7向后端移动，并将支架6向后端移动，便可检查支撑套2以及内芯部件的情况，使连接器相比现有结构具备可维修性。
综上所述，本发明在现有连接器的基础上，使用支撑套2作为粘接套3与插头组件1之间的分支部件,取代原有的分支结构，在保留粘接套3的步进浮动结构的基础上，增加二级浮动功能，实现两级浮动功能，对插头的一级浮动结构进行补偿，同时内芯插头可沿任一径向摆动，实现多个方向的浮动功能，解决了原有结构只能沿单一方向轴向偏摆的问题，同时解决了现有连接器装配要求过高、产品使用故障率高的问题，并提高了连接器的可维修性。
尽管已经展示和描述了本发明的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例 进行多种变化、修改、替换和变型，本发明的范围由所附权利要求及其等同物限定。
